MACHINE WRENCH.

Application filed September 13,-1921. Serial No. 500,308.

T0 all fic/1.0m, 'it may con/cern Be it known that we, RUDOLPH KLEIN and Grenen B. Errani., citizens of the United States, residing at Fults, in the county of Monroe and State of Illinois, and Valmeyer, in the countyv of Monroe and State of Illinois, have invented certain new and useful lm proveniente in Machine Wrenches, of which the following is a specification.

The invention appertains to certain improvements in machine wrenchesl generally, and more particularly to a type of the same adapted forthe tightening or loosening up of the' nuts of the bolts of railroad rail. joints. e

rllhe principal object of the' invention is to provide for a wrench as characterized, and one of a construction and arrangement designed to greatly facilitate 'the work ofthe tightening and loosening` up of the usual fas? tening bolts of railroad rails, and` which is extremely durable, efficient, easy and rapid in operation.

With the foregoing and other objects in View, the invention resides ,in the certain new vand useful construction, arrangement and operation of parts, as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawing, in which y Figure 1 is a side elevation of a preferred embodiment of the machine wrench,

Figure 2 is a front elevation.. thereof,

Figure 3 is a top plan view thereof, and,

Figure 4 is an enlarged sectional detail of the wrench socket per se.

Referring Lto the drawings, wherein similar characters of reference designate corresponding parts throughout the several viewsA thereof, the numerals 10 and 11 Aindicate a pair oi vertically spaced frame bars or stand ards each formed to provide laterally `offset lower foot yportions, l0" andv 11, respectively, and the same are connected together, slightly downward, fromtheir upper ends,lby: means of a transverse bar l2. and. immediately above the'olfset foot portions 10 and 11, by means of a lower transverse bar 13. The vertical bars or standards 10 and 11 are Vpreferably formed of suitable lengths of I-beams, or other similar angle iron or steehand with the foot portions 10 and 11, and the cross bars 12 and 13, constitute the main frame of the machine wrench. Extending laterally from the 'lower ends and foot portions of the vertical bars-or standards v10 and 11, is an auxiliary frame formed of upper and lower pairs of horizontal members or bars 14. and 15, respectively, an outer vertical pair of members or bars 1G .connecting the outer ends 60 of the pairs of upper and lower members or bars 14- and 15, and an outer pair of upper and lower horizontal members or cross bars 17, the corners of the upper parts of this frame, as formed by the connecting portions of the upper pair of members or bars 14 and the uppeil of the cross bars 17, beingsupported from the lower ends of a pair of brace members or bars 18 extending diagonally upward and connecting the standards l0y 70 and llon the main frame at points below the upper ends thereof. f

y Thetwo frames thus constructed and arranged constitute the entire. frame work of themachine wrench, and the same is tow75 be positioned over a rail joint in amanner so that the lower ends of the standards 10 and 11 rest directly upon thev ball of the rail or rails', with thejolfset foot portions 10 and 11 thereofdepending to one side of 80 the latter and resting on the upper face ofA one flange of the rail vor rails, or on the ties supporting the same, the, lower auxiliaryv frame extending outwardly from the rail or rails on the side of the frame from whieh'the 85 nuts are. to bethreaded onto the bolt fas'- tenings at the joint of adjacent rail sections, or unscrewed therefrom. For securing orotherwise clamping the framework in operative position, a pair of oppositely disposed clamp levers 19 and 2O are provided, and each are 'formed with lower angularly offset foot portions 21 and 22 respectively, and are pivoted as lat 23 and 24 to the standards 10` and 11, the'foot portions 21 and 22 en- 95 gaging the side of the rail or rails opposite to that ,of the foot portions 10 and 11, of the standards 10 and 11 of the framework, when operated. The levers 19v and 2() have theirupper free ends pivotally connected as 1.00 at 25 and 26 to the upper free ends of a pair of manually operated levers 27 and 28, which are curved for a distance downwardly from the pivot connections 25 and 26 and terminate in straight lower portions having 1405 hand grips 29'and 30 at their free ends,respectively, the leversV 27 and 28 being pivoted as at 31 and 32 to the st-andards 10 and 11, and to facilitate the manipulation of these levers, the hand grips 29 and 30 are transversely 110 grooved or serrated as shown. In position# ing the framework of the machine on the v Q50 the operating vmedium of the". mechanis1n,
